The Grammy winner confessed that he realized his womanizing ways and public comments about his past love life made him look like a douche and that he is a different person now.

“John has had his eye on Katy for a while," the insider dished. "The best way he thought he could do that was by dispelling his past reputation as a lothario. He’s never been short of female attention."

"In the past he's always been quick to milk that at every opportunity. But John realizes now that it made him appear a bit of a douchebag and an unattractive catch. He knew he had to change his ways."
